Hello,
after updating my Cerbo GX from 2.92 to 2.93, I get occasional timeouts while reading registers periodically. Exactly every 45min, my client (ioBroker) reports an "undefined" Modbus error, resulting in a timeout. Immediate reconnection works like a charm for another 45min.
Is anyone aware of this?
I have the same issue but with Home Assistant. In Home Assistant it could be a bugy Python library, but in your case with IoBroker (JS) I don't know? https://github.com/home-assistant/core/issues/88800
I did have a look at the Release note of the versions 2.92 to 2.93 of Venus GX, but couldn't find any direct issues. But in 2.93 they changed something which could ev. cause the issue:

Restore Modbus-TCP register 31, VE.Bus State. Per a recent version, that register returned "Ext. control" which broke customer implementations. Now the register will return the usual status (Bulk, Absorption, Float, etc) again, when the inverter/charger is in fact externally controlled by a smart battery.
But there where some major changes to Modbus TCP in v2.90 – September 12th 2022. Because I do have Autoupdate I'am not quite sure when mine gets a new version.
